Title: Cash boxes for coin-freed apparatus
Inventor: BURRETT KENNETH FREDERICK
IPC: G07F9/06
Filed: 1963-02-19
Abstract: 1,080,872. Coin boxes for coin-freed apparatus. UNITED GAS INDUSTRIES Ltd. May 19, 1964 [Feb. 19, 1963], No. 6612/63. Heading G4V. A cash box for a prepayment meter has a shutter 16, Figs. 4 and 6, which closes over a coin receiving slot 14 into a locked position upon operation of a handle 22 for releasing the box from the apparatus, the arrangement being such that when the box is delivered to a depot for emptying purposes, the locking mechanism of the shutter can then be so set that on replacing the box, operation of the securing handle 22 causes the shutter to move to its open position. When the shutter 16, which is secured to a hollow cylinder 15, is moved to the closed position by the handle, a pawl 25 springs into position to lock it against return movement. At the depot, an access door 34 is removed and a resetting arm 30, which is loaded against free movement by spring or friction, is moved by a knob 32 into position adjacent the shutter where it presses aside a pawl 35. Upon replacement of the box, the handle causes both the opening of the shutter and the return of the arm 30. The shutter may be operated by rack- and-pinion instead of a spindle 19 and a coindeflector may be provided inside the box. As shown in Fig. 2, a shutter 8 is also provided for the discharge slot 5 of the meter and is secured to a cylinder-lock 6, 7 which fits inside the cylinder 15 and on to a key 23 projecting upwardly from a support 17. The shutter is so formed that it covers securing screws 9 (10) when closed and it may be arranged at the end of a shoot so as to permit a number of coins to collect in the meter when the box is removed.
Patent GB-568535-A (GB)
Title: Heat insulating materials and the like
IPC: C08J9/00
Filed: 1943-04-23
Abstract: Material suitable for heat insulation is obtained by associating coarse particles of a low density cellular material having a basis of a thermoplastic cellulose derivative with a partially polymerised synthetic resin, and subjecting the resulting composition to the action of heat and slight pressure so as to cause the synthetic resin to undergo further polymerization and bind the cellular particles into a firm coherent mass.  The cellular material employed may be a product resulting from causing a cellulose ester or ether to absorb a liquid having a solvent, swelling, or softening effect, subjecting the ester or ether containing the liquid to a high pressure at an elevated temperature, and releasing the pressure quickly to permit rapid vaporisation of the liquid.  Alternatively, the cellular material may be obtained by incorporating a solid capable of producing a gas by heat or chemical treatment in a viscous solution of the cellulose derivative, and then after setting or partial setting of the solution, treating the mass to generate a gas and produce a cellular structure.  The cellular material may also be obtained by incorporating water-soluble salts in the cellulose derivative composition and extracting them by means of water after the composition has been shaped and set.  The resinous binding agent may be a phenolformaldehyde, urea-aldehyde, polyvinyl ester, polyvinyl halide, indene, or styrene resin.  The resin may be applied as a solution in a volatile solvent.  The insulating material may be shaped between flat moulding surfaces into the form of a board or it may be extruded.  Heat may be applied during or after extrusion.  The composition may contain plasticisers for the cellulose derivative. It may also contain dyes, pigments, or fillers, e.g. cotton, flax, hemp, jute, ramie, or silk fibres, or cork, sawdust, wood shavings, clay, or asbestos.  In an example, cellulose acetate is ground to small particles and then butanol is incorporated.  The material is then placed in a mould and subjected to heat and pressure.  The pressure is quickly released and the material expands and forms a solid cellular material which is then cut into small cubes and mixed with a solution of a partially polymerised phenol-formaldehyde resin in diethyl ether. The mixture is placed in a mould and heated under a slightly increased pressure at 150 DEG  C. to cause further polymerisation of the resin and to obtain a mass of the cellular particles agglomerated by the resin binder.  The material may be cut, sawn or nailed.  Partially polymerised phenol-formaldehyde resin may be made by heating formalin solution with phenol to boiling under reflux in presence of sulphuric acid.  Heating is stopped and after a few minutes the polymer separates from the solution.  The acid is neutralised with sodium carbonate and the resin is washed with water. It is soluble in acetone and diethyl ether.

Patent GB-996752-A (GB)
Title: Improvements in or relating to discharge valves for finely divided solid materials
IPC: B65G53/46
Filed: 1963-02-19
Abstract: 996,752. Pneumatic conveyers. COLLECTRON Ltd., and E. WHALLEY. Feb. 19, 1964 [Feb. 19, 1963; March 26, 1963], Nos. 6661/63 and 11968/63. Heading B8A. In a discharge valve 10, Fig. 1, for solid material, comprising at least one pair of hinged flap valves 13, 14 arranged in series for releasing material in batches between regions at different pressures, means are provided for equalizing the pressure on each side of the flap valves so that they fall freely under gravity when the closing pressure is removed. In the example of Fig. 1, the valves 13, 14 are closed by rollers 27 on arms 25 for engagement with wedge-shaped cams 24 on the rear faces of the valves. The arms 25 are also coupled by chains 32 to coilspring type blow-off valves 29 arranged so that movement of the arms 25 to remove the closing force of the flap valves 13, 14 causes a deflection of the blow-off valves 29 to equalize the pressures. The arms 25 are operated sequentially by cams and links and coil springs are arranged between the linkages for the upper and lower arms 25 so that movement to release the closing force on one flap valve, increases the closing force applied to the other. In a modification, a flap valve 58, Fig. 4, is pivoted on a shaft 61 mounted in slotted holes 63 and is loaded near the pivot by a coil spring 71. The arrangement is such that removal of closing force by roller 64 as it disengages from cam 65 permits the spring 71 to pull the valve 58 away from its seating and equalize the pressures before the valve fully opens. The pivot shaft 61 is also enclosed within a tubular easing 74 (not shown) arranged between the pivot bearings 62 to prevent solid material reaching the slotted holes 63. In a further modification a small cut-out portion 84, Fig. 7, of the flap valve 82 is resiliently attached to the flap valve by a flexible member 87 such as a rubber tube held in compression by a tension rod (not shown). The cut-out portion 84 is coupled by a chain 88 to the actuating arm 89 so that movement to release the closing force deflects the portion 84 to open a small section of the valve seating and equalize the pressures before the whole of the seating is withdrawn.

Title: Improved means for unfastening or opening doors
IPC: E05F1/10
Filed: 1936-03-07
Abstract: 469,569. Door &c. fastenings. NEWMAN & SONS, Ltd., W., and SHEAD, H. C. March 7, 1936, No. 6891. [Class 44] Relates to the construction of door-fastenings of the type in which the fastening is released by electromagnetic means the door being opened, when released, by spring means, and provides for the unfastening of double doors by simultaneous release of a pair of levers when the magnet is energized. The invention is described as applied to the double doors of a fire-station, each door having a pair of hinged leaves 1, 2 which fold together in known manner when the door is opened by springs 5, and each door is held by top and bottom bolts 6, 7 having grooves engaging pins 9, Fig. 8, on a disc 10 operable by a handle 11 to shoot the bolts. As retraction of one bolt causes retraction of the other, release mechanism is provided only for the upper bolt. The socket 25 into which the upper bolt shoots contains a plunger 26 normally held raised by the end of the bolt. The plunger has pin-and-slot connection at 27 with a member 29 pivoted at 30 and having a surface 31 bearing against the end 32 of a horizontally slidable rod 12, the other end of which extends into a casing 14. Rod 12 has a length-adjustment screw sleeve 22 and is loaded by a compression spring 19 preferably housed in a telescopic casing 44, 45. The inner end of the rod is normally held with the spring in compression by means of a hook 34 on a lever 36, engaging the end of a rib 33 on the rod. The lever, pivoted at 35, is held in engagement by a pawl 43 on the armature 39 of an electromagnet 13 overlying the inner ends of the arms 36. When the magnet is energized pawls 43 are withdrawn and springs 19 shoot rods 12 outwards so that members 29 are operated to depress plungers 26 and force bolts 6 out of their sockets 25. During release movement each arm 36 is thrown upwards in a slotted guide 37. The parts are reset when the doors are again bolted by handles 11, each arm 36 momentarily moving the corresponding pawl out of its path. Casing 14 and electromagnet are common to both rods 12 of the two doors and the pawls 43 are provided so that fastening the second door does not move the armature and release the first door. A modification is described in which movement of rod 12 is communicated to member 29 by wire transmission. According to the Provisional Specification the fastening may be used on a single door, the pawl being omitted and the armature acting directly.

IPC: F04D29/06
Filed: 1953-03-18
Abstract: 750,311. Centrifugal pumps; elastic fluid turbines. THOMPSON PRODUCTS, Inc. March 18, 1953, No. 7479/53. Classes 110(1) and 110(3) A pump assembly comprises a pump impeller and a turbine wheel on a shaft journalled in a pair of bearings spaced apart in a hollow casing, a charge of lubricant being packed in the casing; spacer means between the bearings form, together with the shaft a restricted flow path for the lubricant. A centrifugal pump impeller 14 is driven by an air turbine rotor 16 through a shaft 13 journalled in bearings 27, 28. The bearings are spaced by a ring 37 and spring-loaded by an annular spring 50. Lubricant, such as grease, can be packed into the space between a seal 18 and a seal bushing 23 through an inlet 32, an annular passageway 33 formed in the nozzle ring 20 of the turbine, and a radial recess 36 in the bushing 23. The bushing 23 is preferably of a porous material which is impregnated with grease or other lubricant. Segmental projections 39 carried by the shaft 13 and projecting into an annular recess 40 in the spacer ring 37 form an impeller which impels lubricant through the bearings by way of the clearance 38 between the shaft 13 and the spacer ring 37. The projections 39 are of magnetic material, so that their movement through a magnetic field set up by a pair of coils 41 induces a signal in conductors 42. If the turbine exceeds a limiting speed, the signal, which is a function of the speed of the shaft 13, operates a relay controlling the opening and closing of a solenoid-actuated valve. The valve controls the admittance of air from the supply pipe of the turbine to a pneumatically actuated valve which shuts off or reduces the supply of air to the nozzle box. Alternatively, the signal may be used to energize an electric motor which actuates a valve controlling the air supply to the nozzle box. Specification 750,387 is referred to.

Title: Method of adjusting cathode ray tube scanning apparatus
IPC: H04N5/257
Filed: 1965-02-22
Abstract: 1,090,341. Cathode-ray tubes. FERNSEH G.m.b.H. Feb. 22, 1965 [Feb. 22, 1964], No. 7479/65. Heading H1D In a flying spot scanning arrangement the tube is first adjusted, by the use of biasing currents through its coils, to ensure perpendicular incidence of the undeflected beam upon the tube screen, whereafter the tube is moved bodily to position the centre of the scanning pattern on the axis of the optical system. The beam 2 is aligned parallel to the axis of the focusing coil 4 by an alignment coil 3. whereafter it passes through a dynamic focus correction coil 9-to which a waveform having current proportional to the square of the angle of deflection is applied in operation-and deflection coils 5, before striking screen 8, the light from which is modulated by a slide or film 11 and projected on to the photo-cathode of a photo-cell or television camera 14. Perpendicular incidence of the beam upon the screen 8 at the centre of the scanning pattern is produced by adjusting biasing currents either through deflection coils 5 or through a second set of alignment coils (not shown) disposed between coils 4 and 5; this ensures that the focal plane of the focused beam, as corrected by the dynamic deflection coils, coincides with the screen 8, and hence that the spot is of uniform brightness over the whole of the scanning pattern. Subsequent bodily displacement of the tube to bring the centre of the scanning pattern on to the axis of the optical system ensures that the whole of the slide or film 11 is scanned.
